(Cl. 1GO- 33) 1 Claim. 1

This invention relates to window blinds and more particularly, it relates to improvements in the method of mounting and housing window blinds of various designs, such as Venetian blinds. The invention will be known as the Hi-Lite Sill Blind and comprises all of the desirable features demanded in window blinds, combined with a wide eld of applications, as well as an inherent element of novelty and utility which will produce new and benecial results.

One of the primary objects of the invention is to provide a window blind installation whereby sun, daylight and ventilation can be adjusted to a desired degree as often through the day as required and at the same time, maintain complete privacy.

Another object of the invention is to eliminate the ever present danger of injury inherent in the existing method of installing and repairing blinds by means of stepladders, tables, chairs or the like.

Still another object of the invention resides in providing means whereby the rays of the sun may be cut off from eye level without completely closing the blind, with special reference to railway coaches, pullmans, Steamship cabins, oices and motor vehicles, which now are either too dark or too sunny.

Yet another object of the invention is to improve the general appearance of living rooms, offices or the like by a window sill installation of blinds, whereby the unsightly overhead installations are eliminated.

Another object of the invention is to increase the life of blinds to a substantial degree by avoiding frequent cleanings by means of a housing whereby the blinds are protected from dust and other impurities in the air.

The invention will also effectively protect rugs,

furniture, paintings, etc. against the rays of the sun.

Yet another object of the invention resides in providing means whereby proper light and ventilation may be provided, so essential, especially in schools and hospitals.

The invention will also, to a degree, reduce the iire hazard inherent in an overhead installation of window blinds.

In order to enable those skilled in the art to have a full and complete understanding of the, invention and its various structural and functional advantages, in the accompanying drawings, forming a part of this specilication, and throughout the views of which like reference characters refer to the same parts, I have shown a desirable and preferred embodiment of the invention, although the latter is susceptible of many other embodiments.

In the drawings:

Figure 1 is an elevation of a window with a Venetian blind partly raised, applicable to new building construction.

Figure 2 is an enlarged section on the line 2-2 of Figure 1, showing the installation of a Venetian type blind in a window sill, especially applicable to new building construction.

Figure 3 is an enlarged sectional view on the line 8-3 of Figure 1 showing the housing and the blind folded therein.

Figure 4 is an enlarged view of the pulleys with automatic stop.

Referring to Figures l to 4, there is shown a Venetian type window blind installation especially applicable to new building construction, comprising a housing E4 adopted to receive Venetian blind l5. The folded blind is completely concealed and protected in the housing by means of a cover I6 fitted in longitudinal grooves in stool Il and nailing strip i8 as shown in Figure 3.

The unsightly, dust-collecting overhead installations are avoided, necessitating frequent cleanings and dusting, thus eliminating labor and adding materially to the life of the blind.

The blind can be raised, lowered and locked at any given height by means of cords I9 and 20, secured to the head rail 2| adjacent to the ends thereof. The cords run over pulleys 22 vand 23, the latter being provided with an automatic stopv 24. The automatic stop, as shown in Figure 4, engages immediately the raising cord is released from the hand, irrespective of the position in which the cords are held. Disengagement is effected by pulling the cords to the left.

It is to be understood that the foregoing description and the drawings are only for the purpose of illustrating the invention set forth, which invention is to be hunted only by the scope of the appended claim in which it is intended to claim all novelty inherent in the invention, as broadly as the prior art permits.

I claim:

A built-in housing for Venetian blinds, comprising a window sill recess adopted to receive the slats of a blind in collapsed position thereinto, a nailing strip forming the bottom of the recess and means to pr-otect the blind from suspended matter in the air.
